Three reported PDF bugs from the customer-facing email package:
1. Invoice body was empty — Odoo 19 sets display_type='product' on
regular invoice/SO lines (was empty string in 18.0). Both
report_fp_invoice.xml and report_fp_sale.xml only matched
`not line.display_type`, so every product line was skipped.
Fixed both portrait + landscape variants to also match
display_type == 'product'.
2. CoC PDF was a bare 30 KB header — _fp_generate_cert_pdf was
rendering action_report_coc, which is bound to portal_job and
has minimal content. Rewrote to use the rich fp.certificate-bound
report (action_report_coc_en / action_report_coc_fr based on
cert.partner_id.lang) and slugged the filename to
CoC-<Customer>-<CertName>.pdf so the email attachment reads
nicely instead of CERT-00123.pdf.
3. Thickness cert was an exact duplicate of the CoC — the CoC
template already embeds thickness readings. Skip thickness cert
creation entirely when the customer also wants CoC; only create
a standalone thickness cert when the customer opted out of CoC.
Also: dispatcher in fp_notification_template now prefers
portal_job.coc_attachment_id (the rich one we just generated) and
falls back to rendering action_report_coc_en against fp.certificate
by partner.lang — never the bare portal-job report.
